Phosphorus (P) is an essential element to all life, being a structural and functional
component of all organisms. 1-4 P provides the phosphate-ester backbone of DNA and …

Discrepancies between estimates of oceanic N 2 fixation and nitrogen (N) losses through
denitrification have focused research on identifying N 2-fixing cyanobacteria and quantifying …

Rising ocean temperatures will alter the productivity and composition of marine
phytoplankton communities, thereby affecting global biogeochemical cycles. Predicting the …

Climate change will alter concurrently many environmental factors that exert control over
oceanic phytoplankton. Recent laboratory culture work, shipboard experiments, and field …

The cyanobacterium Trichodesmium is an important link in the global nitrogen cycle due to
its significant input of atmospheric nitrogen to the ocean. Attempts to incorporate …

We examined the physiological responses of steady‐state iron (Fe)‐replete and Fe‐limited
cultures of the biogeochemically critical marine unicellular diazotrophic cyanobacterium …

Approximately 50% of the global natural fixation of nitrogen occurs in the oceans supporting
a considerable part of the new primary production. Virtually all nitrogen fixation in the ocean …

In late summer, massive blooms and surface scums of cyanobacteria emerge regularly in
the Baltic Sea. The bacteria can produce toxins and add bioavailable nitrogen fixed from …

Plankton community models are critical tools for understanding the processes that shape
marine plankton communities, how plankton communities impact biogeochemical cycles …

The globally distributed colonial cyanobacterium Trichodesmium and unicellular
diazotrophs including Crocosphaera together carry out the majority of marine biological …
